The radar is one of the best in the world and can reportedly detect the F-22 from 100km away.
The fact that Egypt has signed an agreement for the supply of Su-35 fighters, “Kommersant” told two top managers of defense industry enterprises. According to them, the relevant agreement, which implies the supply of “over two dozen machines” and aviation aids to them in the amount of about $ 2 billion, entered into force at the end of 2018, and the supplies themselves can begin as early as 2020–2021. The interlocutors of “Kommersant” refused to disclose the cost of the contract, but noted that the contract “guarantees the capacity utilization of the manufacturer of the machine, the Komsomolsk-on-Amur Aviation Plant, for several years ahead.” At the same time, one of the interlocutors of “Kommersant” stressed that the production capabilities of the factory line allow the company to produce about 20 such machines for the needs of Russian aerospace forces without problems in 2019–2020. In the Federal Service for Military-Technical Cooperation and Rosoboronexport (a special exporter of Russian arms), “Kommersant” refrained from commenting on this topic.

Sukhoi Su-35S: Capabilities Out of This World
A Generation 4++ Fighter Jet
The Sukhoi Su-35S carries a 30mm cannon, has 12 hard points and can detect targets at more than 400 kilometers, while its radar can track up to 30 targets simultaneously. The fighter has range in excess of 3,500 kilometers without refueling. The world’s most powerful Fourth-Generation fighter’s standout features include new engines, avionics and radar.
Engines
Use of high-thrust engines is a significant differentiator of Sukhoi Su-35 from predecessor Su-27 family jets. The new engines were developed by NPO Saturn, a
UEC subsidiary, and are known under the 117S designation.
The new engines are essentially a deep upgrade of production AL-31F engines, with fifth-generation technologies used in the upgrade. The upgrade has increased the engine’s thrust by 16% to 14,500 kgf with afterburners and to 8,800 kgf maximum dry thrust. The engine has a significantly improved expected life (by a factor of 2x – 2.7x) compared to the production AL-31F: from 500 to 1,000 hours between repairs (and to 1,500 hours running time before the first overhaul), with the total expected life increasing from 1,500 to 4,000 hours.
Two engine manufacturers – the Ufa Engine Manufacturing Company (UMPO) and Rybinsk-based NPO Saturn – will manufacture 117S engines in cooperation with each other. The manufacturing partners, NPO Saturn and UMPO, have decided to share equally the scope of work to manufacture 117S engines.
Avionics and Equipment
The avionics used in the new jet are a completely new system of onboard electronics. The entire complement of Sukhoi Su-35 electronics is integrated into a single system.
Avionics and other equipment are integrated into a single cohesive system by an information processing and control system, which comprises two digital CPUs, interface and data conversion systems, and a head-up display (HUD) implementing the glass cockpit concept.
The Su-35 has two MFI-35 large color multi-functional LCDs, a multi-functional panel with an integrated display processor, a wide-angle collimated head-up display superimposed over the windscreen and a control panel in the cockpit.
These indicators and a range of other avionics systems of the aircraft were developed by the Ramenskoye Instrument Design Bureau, also a Concern Radioelectronic Technologies (KRET) subsidiary.
KRET engineers also designed a new navigation system for the fighter jet – the BINS-SP-2 strap-down inertial navigation system.
The navigation system can identify the aircraft’s location independently from satellite positioning and without communicating with ground-based systems, at accuracy levels double those offered by earlier versions. BINS-SP-2 has an expected operating life of 10,000 hours, nearly double that of currently available comparable navigation systems.
Incidentally, this state-of-the-art navigation system, created from scratch by
KRET subsidiaries, will be also used in the Fifth-Generation advanced front-line aircraft system.
Airborne IRBIS Radar
While lacking an APAR, the Su-35 radar system can detect targets at distances up to 400 kilometers, as well as tracking up to aerial targets and engage up to eight of these targets simultaneously.
Sukhkoi Su-35S has owes these capabilities to its new Irbis phased-array radar control system. The system was developed by Tikhomirov Instrument Engineering Research Institute, a KRET subsidiary, and is being manufactured by the Ryazan State Instrument Factory, another subsidiary of KRET.
The state-of-the-art system enables Sukhoi Su-35S to detect quickly and track simultaneously up to four ground targets or up to 30 airborne targets, as well as engaging up to eight airborne targets at the same time. Besides, the radar control system has the friend-or-foe identification capability for aerial and maritime objects, is capable of identifying the class and type of airborne targets and take aerial photos of the ground.
The system can be used in any weather at any time of the day, and remain effective in the face of interference, either natural or organized by the enemy electronic warfare systems.
An oscillator with peak power output of 20 kW used in the passive phased array radar makes Irbis the most powerful radar control system in the world.
This puts the Sukhoi Su-35S radar system on par with the best state-of-the-art international designs, and ahead for most US and European active and passive phased array radars.
